the archaeological evidence suggests that iran has been one of the first origins of sheep domestication in the world. this study aims to investigate the genetic diversity of indigenous iranian sheep breeds using mitochondrial dna (mtdna) and to explore the evolutionary history of sheep domestication in iran. single nucleotide polymorphism (snp) markers in the control region of mtdna were used t...

The Ponto-Caspian mysid Limnomysis benedeni was first recorded in Lake Constance in summer 2006, and a stable population developed at the site of discovery. Although this mysid is common in the Rhine and Danube rivers, little is known about its ecology and impact in systems of invasion. We investigated the autecology of L. benedeni in habitatchpice and food experiments. In the habitat-choice ex...

The inflationary cosmology [1] makes a prediction for the spectrum of energy-density fluctuations in the early universe [2]. The result is the scale-invariant Harrison Zel'dovich spectrum [3] : fluctuations of wavelength L at a tune t ~ Lie (the tune of horizon crossing) are predicted to have an amplitude 6 a which is independent of L. The scale-invariant spectrum is a model-independent predict...
